TAP46 — triticum aestivum

Summary

TRAESCS5D02G142100 (symbol TAP46, TaTAP46-5D) on bread wheat chromosome 5D encodes a TAP46-like protein that binds protein phosphatase 2A and exhibits protein phosphatase regulator activity, protein serine/threonine phosphatase activity, kinase binding, and DNA-binding transcription factor activity. The gene is associated with regulation of TOR signaling, dephosphorylation, translation, nitrogen utilization, and sugar-mediated signaling. It has been linked to stomatal closure, chloroplast avoidance movement, primary root development, stem cell differentiation, and seed germination. Associations with agronomic traits include iron content, phosphorus uptake, cadmium concentration, aluminum response, nitrate sensitivity, seed viability, pollen fertility, flowering time, leaf senescence, root thickness, and responses to osmotic, light, low-temperature, and abiotic stress. The gene is also associated with drought resistance, cold stress tolerance, phosphate deficiency tolerance, and meiotic recombination.
